Wedding Wednesday: How will Prince William's nuptials compare to what his parents did? (vote in our poll)

Are you wondering how Prince William's wedding to Kate Middleton will stack up to his parents' 1981 nuptials? While all details have not been released about the young couple's big day, TLC's "Charles & Di: Once Upon a Time" gives plenty of facts for you to compare and contrast for now.

• Prince Charles and Princess Diana got married in St. Paul's Cathedral on July 29, 1981. Prince William and Middleton will marry inside Westminster Abbey on Friday, which is St. Catherine's Day. It's a day when single women pray that they'll find their future husbands. When William is king, Kate will be known as Queen Catherine. (Growing up, Middleton was called, Catherine.)

• After the wedding, Princess Diana and Prince Charles left in a 1902 State Landau carriage. That same carriage will likely carry Prince William and Middleton when they leave Westminster Abbey. If it rains, it's likely the young couple will ride in Princess Diana's glass carriage, which she rode in to the church before her wedding.

• Princess Diana and Prince Charles were right-handed and they signed their wedding documents after the ceremony. Prince William is left-handed and Middleton is right-handed.

• Princess Diana wore her blue sapphire and diamond engagement ring on her right hand during her wedding. Prince William gave Middelton that same ring as her engagement ring.

• Like Princess Diana, Middleton's wedding ring will be made of Welsh Gold. However, Prince William will not wear a ring, as is the tradition in the royal family.

• Prince Charles proposed in his apartment in Buckingham Palace. Prince William popped the question during a trip to Kenya.

• Prince Charles and Princess Diana had been dating six months before he proposed. Prince William met Middleton in 2001, their romance became public in 2004, British newspapers reported that they split in April 2007, other media reports said they later reunited a few months later in 2007, and Prince William proposed in October 2010, according to CBS.

• Princess Diana turned 20 just three weeks before her wedding. Charles was 32 when he married her. Prince William is 28 and will turn 29 in June. Middleton is 29.

• London designers David and Elizabeth Emanuel made Princess Diana's dress. Rumors continue to fly as to which designer has created Middleton's dress. The first knock-offs of Princess Diana's dress were available five hours after her wedding.

And a few royal tidbits for the road:

• Princess Diana's "something borrowed" was the Spencer Tiara, a gold and diamond tiara that was given to her grandmother in 1919. Another "something old'' were a pair of diamond drop earrings her mother loaned her.

• Princess Diana's "something blue'' was a tiny blue bow the dress designers sewed to the back of her dress.

• Queen Elizabeth and her husband, Prince Philip, are third cousins.

• Queen Elizabeth's father, King George VI, was played by Colin Firth in the movie, "The King's Speech."
